I think so, too. The object of criticism is female pig's feet. Mathilde is the wife of a young civil servant. In order to attend a party, she borrowed a diamond necklace from a friend, but she lost it on her way home. She had to borrow money to buy a new necklace and then give it back to her friend. She worked hard for ten years to pay her debts, and finally realized that the necklace she borrowed was a fake diamond necklace. Alas, the price of vanity.
